A variety of diseased leaves and background noise types are present in images tomatoes captured real-world environments. However, existing tomato leaf disease recognition models limited to recognizing only a single leaf, rendering them unsuitable for practical applications scenarios. Additionally, these consume significant hardware resources, making their implementation challenging agricultural production promotion. To address issues, this study proposes framework that integrates detection...

Due to the powerful ability of data fitting, deep neural networks have been applied in a wide range applications many key areas. However, recent years, it was found that some adversarial samples easily fool networks. These input are generated by adding few small perturbations based on original sample, making very significant influence decision target model case not being perceived. Image segmentation is one most important technologies medical image and automatic driving field. This paper...

As more and multilingual knowledge becomes available on the Web, sharing across languages has become an important task to benefit many applications. One of most crucial kinds Web is taxonomy, which used organize classify data. To facilitate languages, we need deal with problem cross-lingual taxonomy alignment, discovers relevant category in target one language for each source another language. Current approaches aligning taxonomies strongly rely domain-specific information features based...

We consider off-dynamics reinforcement learning (RL) where one needs to transfer policies across different domains with dynamics mismatch. Despite the focus on developing dynamics-aware algorithms, this field is hindered due lack of a standard benchmark. To bridge gap, we introduce ODRL, first benchmark tailored for evaluating RL methods. ODRL contains four experimental settings source and target can be either online or offline, provides diverse tasks broad spectrum shifts, making it...
